the numeral 1 indicates the ged of t 'efmachine, which bed has side plates 2, 2. The bed 1 is firmly mounted u le 8, 3. vOne of said l carries ajsha 4 w 'ch extends 5 transverse v of the machine..h vSaid shaft 4 has kmounted thereon a sprocket 5 on one side l of the machine. Mounted on the shaft 4 on the op osite'sideof the machine is a pulley.

an incompletey of the 'grids passing thereunder.

. and 24 carry a belt 27 of any suitable fabric,

on the bed 1 is a transversely extending shaft 7, upon one end of which 1s a vsprocket 8. A cham 9 'is adapted to transmit power from'the sprocket 5 to the sprocket 8. The shaft 7 -is provided with a 4transversely extending drum 10. Mounted on theother end of the machine is a transversely extendin and rotatably mounted drum 11, which wil preferably be of the same dimensions as the ldrum 10. Mounted on the drums 10 and 11 is a belt 12 which may be of any suitable fabric, preferably canvas. If desired, the belt may consist of a suitable supporting material as for instance, leather, which leather will be covered with fabric. The belt 12 should be heldtaut during service and for that dpurpose the adjusting bolts 13 are provide by means of which the drum ll'may be adjusted longitudinally of the machine. Extending transversel of the machine is a shaft 14, one end of w ich is connected by a suitable chain with the shaft 7. Extending parallel with the shaft 1 4 is a shaft 14". Said shafts 14 and 14'L are connected b gears 15* and 15". Mounted on'the' sha 14, at the end of said shaft, opposite to the -gear 15", is a bevel gear 16 adapted to cooperate with a second bevel gear 17. The

bevel gear 17 is securel mounted on the shaft 18, which operates t ough a universal joint 19 to drive -a shaft 20. The shaft 20 acts through auniversal joint 21 to drive the shaft 22. Mounted on shaft 14* is a 'drum 23. (lo-operating with the drum 23 `with pins 26' which will ride in lslots in the Atrunmons 25, whereby'the drum 24 may yield-in a vertical direction to allow for inequalities in/ the thickness of the battery The drums 23 plefera'bl canvas. AMounted within the cones oft e belt 27 is a board 28. The' belt 10o 27, in the lowermost part of its travel, is

ada ted to contact with the lower side' of sai board 28. Mounted within the conwith-theu per side vof the board 29.

The sha 22 is provided with worms 30 and 31. The worm 30 is adapted todrive the roller 32 through a suitable worm-wheel. The roller 32 isjmounted in 'trunnions 33. lle

The trunnions 33 will be provided with slots which will permit of a vertical movement of the roller 32. `The worm 31 is adapted to drive the roller 34 through a suitable wormwheel. The roller 34 is mounted in trun- 'nions 35. These trunnions 35 will -also be provided with slots, permitting the vertical movement of the roller 34. Preferably, the roller v34 will b e spring-pressed b springs 36, 36, to its lowermost position. e roller 32 may be similarly (spring-pressed to its lowermost sition, if esired. The driving means for t e roller 34 will preferably be so designed that the periphera speed of said roller is less than the speed o translation of the belt 12, whereby said roller will eifectively pack paste into the grids.

, Pivotally mounted' on either side lof the bed 1, preferably on the shaft 14, are two bracket members 37, 37. Said brackets are adapted to carry a roller 38 which will be positively driven from the shaft 14* by suitable transmission means, illustrated in Fig. 2 as a.pair of gears 40 and 41. 'Rie roller 38 is adapted to contact with the belt,27 and will scra oi any excess -of paste adhering to sai belt 27. Also mounted on theV bracketsv 37, 37 is the scraper 39 which will engage-the roller 38 to scrape o the,

pastefrom said roller. The paste'may be collected from the 'scraper 39 in any suitable way. The rollers 32, 34 and 38 which are intended to come in direct contactwith the paste, will preferably be made of brass,

or at least have. a brass surface. The rollers 23, 24, 10 and 11 may be of an vsuitable material, referably hardened steel.

Moun on both sides of the bed are levers '42, 42, pivoted to the 'transversely extendin shaft 1 43. Rotatably mounted in suitab e slots in said levers 42 is a roller 44.

The other ends of said levers 42 are springheld downwardly b means of springs 45, 45. It will be evi ent that the action of the 45, 45, willrur the roller 44 u against the inside sur ace of lthe beltv 41 urging belts 12and 27 together. The board 28 will act as an abutment.`

A mode of operation of the above describedV embodiment of the present invention is substantially as follows. Power will be communicated to the pulley 6 acting through .the s rocket 5, chainf9, sprocket 8, to rotate the rum 10. Rotation ofthe 10 will drive the belt 12 in the ldirection Vindicated by the arrow in Fig. 1. Rotation will also Y toii'i side of the grids. This is a decidedadbe communicated thro h the chain and will drive the belt 27. Furthermore motion win be mmunicsdfrom the sima 14, bevel gears 16 and 17. and shaft 20 to the 'shaft 22. Rotation ofthe shaft 22 acting of the machine as viewed in Fi 1. At the same time, paste will be appli at the roller 34. As t e belt 12 feeds the' grids underneath the r'oller 34, said roller 34 will pack the paste into the grids. The belt.12,.actin,ii;

against the board 29, will'act as a perfectly fiat surface upon whichtlie acking is done. After passing under the rol er 34, the' rids will be carried by the belt 12 in' a left and -direction,- as viewed in Fig. 1, under the roller 32. The roller 32, acting against the belt which is sulpported by the board 29, will further pack t e 'paste into the ids. As

the belt 12 carries the grids fart er to the .left,' they will come between the belts 12 and 27. .At thispoint theboard 28 will act.

grids as they pass along the firmly mounted abutments, will all ield to allow for inualities in the thic ess of the grids. *It will be noted that boards 28 and 29 are shown as overlappin These boards will be spaced apart a s cient distance to permit of the thickest grids which it is desired to use in the machine. As the grids pass out from between!v the 'belts 27 and 12 `at the left hand end of the machine, they willhave been firmly packed with pasteiand the surfaces of thev aste will have been finished.

The belt 2 in service, collect-conmaly, l siderable paste. his paste will be collected from the belt 27 by the roller 3 8, from which it will be sera oi b the scraper 39.

Not only wi l the rol er 38 act as a means for collecting paste from the belt 27, but it will' also `serve to keep the belt 27 taut.

It will be apparent that by the machine andthe method disclosed, any'size grid up to the capacity of the machine or a plu-v ralit offgrids may be fed into th vrollers have a yielding action, various sizes of grids may be used without chan 'ng the adjustment of the various parts.` en the plates leave the machine, they will be perectly finished, requiring no further opera' e machine. ermore, due to the fact that the various tion upon their surfaces. Furthermore,

should there be any incomplete filling of the ids, as through any defect in the paste, such eficiency will at once show up on the botvan for,the followi reasons'.v Thenpaste is applied to the grids from thetwo sides, thev material, meeting in the center, it will' uentl occur that there will bea distinct A e o cleavage down the center of the plate and rliaps an open space therein. Such: deficiencies will'not be iso apparent l .upon inspection for the reason that an 1nspection of the twn Vsurfaces would indicate a perfectly filled grid. According to this invention, however, wherein the paste is applied from one side against an abutment and the sides bein thereafter subjected to a inishin operation, any deficiency in the filling of t e an inspection of the bottom side thereof.
